SHOCK-SORBEE.

Application filed November 1, 1918. Serial No. 260,686.

Fig. 5 is a'view in perspective of the anchor for the shock absorbingspring.

In the drawings above briefly described State the numeral 1 designates aportion of an one of the axles, and 3 indicates. a semielliptic leafspring. One end of the spring in the ordinary automobile, the other endof the spring is connected to a bracket 5 on the frame, by shackle links6. Due to the nature of the present invention however, these links areremoved and applied for a different purpose.

A rigid extension 7 is provided for the end of the spring 3 with whichthe links 6 are usually connected, and although said extension could beconstructed in a number of ways, I have shown only one form forillustrative purposes, such form consisting of a base plate 8 having apair of up-standing cheeks 9 which receive therebetween the usual eye 10on the end of the spring, the bolt 11 which was formerly used forconnecting the links 6 to said spring, bein now passed through the eyeand cheeks to asten the extension 7 to the spring. The inner end of thebase plate 8 extends beyond the cheeks 9 and is suitably shaped to forma shoe 12 underlying the spring 3 to prevent the outer end of said platefrom tilting downwardly. The last named end of plate 8 is provided withan upstanding lug 13 to which the lower ends of the links are pivoted bya bolt or the like 14.

A bell crank lever 15 is received between the upper ends of the links 6and is pivoted thereto by a bolt or other suitable means 16, the upperarm of said lever being inclined upwardly from the fulcrum and pivotedat 17 to the bracket 5. The lower end of the lever 15 is suitablyconnected to one end of a coil spring 18 located beneath the extension 7and the adjacent end of spring 3.

The spring 18 is connected to an eye 19- on a rod 20, said rod passingover the axle 2 at one side of the spring 3, curving downwardly at 21 infront of said axle, then extending laterally at 22 beneath the spring,and finally turning upwardly at 23. The longitudinal portion of the rod20 and its 11 wardly bent end 23 serve to prevent lat- Shock-Absorbersone end of the usual the shackle links prosaid objects in view the inthenormal relation of lever.

- automobile chassis frame, 2 has reference to eral shifting, while thedownward turn 21 1 and one end of a leaf and the lateral extension 22prevent rearward shifting of the rod. An efi'ective anchor for thespring 18 is thus formed and it will be obvious that such anchor may beconstructed easily and inexpensively.

To install the device, it is simply necessary to remove the shacklelinks 6, secure the extension 7 in place by one of the bolts previouslyused on said links, to connect the links to the lug 13 probably bolt, toconnect the links with the lever 15, pivot said lever to the bracket 5,and engage the anchor rod 20 with the sprmg and axle as shown. Underslight strain, the lever 15 rocks upon its fulcrum and the spring 18yields to absorb the shocks, the relatively stifi' leaves of the spring3 then coming into play very little if at all. Under severe shocks, thelever 15 swings until its normally inclined upper end moves downwardlyonto the-checks 9 as shown in Fig. 2. The movement of the lever is thuslimited so that breakage of the sprmg 18 is prevented andthe spring '3then comes into play in the same manner as if the shock absorber werenot employed.

From the foregoing taken in connection with the accompanying drawing, itwill be obvious that although my invention is of comparatively simpleand inexpensive nature, it will be highly ef'ficient and in every waydesirable. Since probably the best results are obtained from the detailsshown and described, they may well be followed, but within the scope ofthe invention as claimed, considerable latitude is allowed for makingsuch minor changes as occasion may dictate.

I claim:

1. In combination with a vehicle frame spring below the same, alongitudinal extension on said end of the spring, a link pivoted to andrising from the outer end of said extension, a bellcrank lever fulcrumedto the upper end of said by the other .wardly at the side link andhaving one end pivoted to said frame, and spring means connected to theother end of said lever for yieldably controlling its movemen 2. Incombination with a vehicle frame and one end of a leaf spring below thesame, a longitudinal extension for said spring having a pair of verticalcheeks receiving said spring end therebetween, a bolt passing throughsaid cheeks and through said spring end, the inner end of said extensionhaving a shoe underlying the spring to prevent downward tilting of theouter end of said extension, a link pivoted to and rising from the outerend of said extension, a bell crank lever fulcrumed to the upper end ofsaid link and having one end pivoted to said frame, and spring meansconnected to the other end of said lever for yieldably controlling itsmovement. v 1

3. A structure s specified in claim 1, the upper end of-said levernormally inclining upwardly from .said extension and bein movabledownwardly onto the latter under severe strain, whereby to limit theswinging of the lever and prevent injury of said spring means.

4. The combination with a vehicle frame, an axle, a vehicle springsecured to said axle, and shock absorbing means associated operativelywith said spring and frame and including a coiled spring; of a rod towhich said coiled spring is anchored, said rod extending over the axleat one side of the vehicle spring, curving downwardly at one side ofsaid axle, then extending laterally beneath the vehicle spring, andfinally turning upof said vehicle spring remote from the body portion ofthe rod.

In testimony whereof I have hereunto set my hand.
